Name with Game
Cami's right on with referring to hobbies, etc., for names.
I've had several boxers and always think of what the name sounds like to others when I call them out loud in public. Examples if they help:
Had a tough looking boxer male but didn't want everyone to be afraid of him so I called him Buddy. Everyone always thought he liked them instantly, but he was just responding to his name. (Note: he was very well trained & didn't run off with strangers just because his name was called.)
Doctor friend called his boxers, Nip and Tuck. Almost a calling card.
Had two boxers and two cats: Sampson & Delilah, Romeo & Juliet. Besides being cute, that's the only way I could quickly recall their names at first.
Another friend named his boxers, Bud & Wiser, run it through fast for a laugh.
My sister was into martial arts so we named her boxer Kempo.
I love the name Maximus for a boxer. Favorite movie characters are a good sources of names.
Think of a name that brings a smile to everyone's face when you call your dog's name aloud and you just can't go wrong.
